Chapter 1 Logical Domains

1.1 The Basics of Logical Domains

Logical Domains is a virtualized hardware environment operating on the SPARC platform. It can divide one platform into multiple virtual server environments, and each virtual server can run its own independent instance of the operating system.

Figure 1.1 Logical Domains

Note) It is advisable to confirm license policy for Operating Systems in Domains. Different versions of

Operating Systems may require different licenses.


1-2 C120-E534-15EN

1.2 Differences between Partitioning Methods

Hardware partitioning, can be used for SPARC Enterprise M4000 and upper models. Also, with the Solaris OS function, Solaris Containers can be used for on all SPARC Enterprise all models. Each partitioning method has the following features.

1.3 The Basics of Hypervisor

UltraSPARC T2/T2 Plus, SPARC T3 and SPARC T4 processors have the following three operation modes. • Nonprivileged mode. (User mode) • Privileged mode. (Supervisor mode) • Hyperprivileged mode. (Hypervisor mode)

Figure 1.2 Operation modes of Ultra SPARC T2/T2 Plus, SPARC T3 and SPARC T4 processors

The Hypervisor acquires control authority from the kernel (Supervisor mode) if required. It supervises multiple kernels or simultaneously with the same way as multiple user processes are controlled in one kernel.

The hypervisor is a part of the firmware that is stored in EEPROM.

1.4 Role of the Domain in Logical Domains

C120-E534-15EN 1-5

1.4 Role of the Domain in Logical Domains In Logical Domains environment, Logical Domains are classified into four types according to roles.

• Control Domain This is a domain in which the Logical Domains Manager is installed. This domain can create and manage other domains, and allocate a virtual resource. Only one Control Domain exists in one server.

• Service Domain This is a domain that provides virtual device services for other domains working with the I/O Domain. The virtual device services contain disk, network, and console.

• I/O Domain This is a domain that between SPARC Enterprise models physical I/O devices including PCI cards, and can directly access to them. Maximum number of I/O Domains differs according to models you are using. You can own PCIe slots and onboard PCI devices by owning the PCI root complex or by using the PCI Express (PCIe) direct I/O functionality. For details, please refer to "Chapter 6 Setting Up I/O Domains" in "Oracle VM Server for SPARC 2.2 Administration Guide". http://docs.oracle.com/cd/E35434_01/html/E23807/usingpcibuseswithldoms.html

• Root Domain The PCIe root complex is allotted to the root domain. The root domain is also an I/O domain, possesses the physical I/O devices and those can be directly accessed through it. The number of retainable root domains varies according to the platform.

• Guest Domain This is a domain that is managed by the Control Domain and uses the virtual device services provided by the I/O Domain and Service Domain.

Independent OSs run in each logical domain. One Logical Domain can have several roles. In general, the Control Domain is I/O Domain and Service Domain. In this document, this is called as the Control Domain. In addition, one Guest Domain is used as I/O Domain and Service Domain, but another Guest Domain may not. In this document, the former is called as the I/O Domain, the latter is called as the Guest Domain.

http://docs.oracle.com/cd/E35434_01/html/E23807/usingpcibuseswithldoms.html


1-6 C120-E534-15EN

1.5 Resource Components • Virtual CPU

Virtual CPUs can be allotted in units of threads upto 128. The Virtual CPU can be transferred between domains without stopping them. The operations for addition/deletion can be operated on the Control Domain.

• Memory The unit of minimum physical memory segment that Solaris OS manages is 4MB. You can allocate memory by 4MB to each domain.

• Virtual Disks The virtual disk service (vds) controls physical disks to provide each domain with the virtual disks. You can use the following types of disk as entities of the virtual disks. However, there are some restrictions depending on the type of entities.

- Physical disks - Disk slices (Boot disk is not available for any releases older than Solaris10 10/08.) - UFS files - Loopback file system (Not available for boot disk.) - ZFS volumes/ZFS files (supported by Logical Domains 1.1 or later)

• Virtual Console You can access the virtual consoles of each domain using the console service of the Control Domain and telnet command.

• Virtual Network A Virtual Network device (vnet) can be defined for each domain. The Virtual Network device interact with other domains or physical networks via the virtual switch (vsw) of the Service Domains.

• Virtual Cipher Unit You can virtualize the cipher unit that UltraSPARC T2/T2 Plus processors or SPARC T3 processors has per 1 core, and allocate it to any domain. (This is not available as of publishment of this document.)

CAUTION

Some functions are not supported by Fujitsu. Refer to " Chapter 1 Oracle VM Server for SPARC 2.2 functions are not supported" in "SPARC Enterprise Oracle VM Server for SPARC Important Information".




C120-E534-15EN 2-1

Chapter 2 Logical Domains Application

2.1 Policy on Selecting Partitions

Fujitsu supports three partitioning methods: Logical Domains, hardware partitioning and Solaris Container. Select the appropriate method according to the operation features.

Figure 2.1 Partitioning methods


2-2 C120-E534-15EN

2.2 Application Purposes of Logical Domains

Logical Domains can be used for the following purposes:

2.2.1 Upgrade from the previous Solaris server

• With one SPARC Enterprise T5120 (4 cores server), maximum three SPARC/Solaris server (800MHz, 2CPUs) units can be consolidated.

• With one SPARC Enterprise T5120 (8 cores server), maximum three SPARC/Solaris server (800MHz, 4CPUs) units can be consolidated.

Figure 2.2 Logical Domains application example (Upgrade from Solaris server)

2.2.2 Proper Use of Logical Domains in the Development/debug machines

Domains for these purposes are to be kept separate from production domains. Using the Logical Domains technology, one can create separate domain for development.

Figure 2.3 Logical Domains application example (proper use of Logical Domains in development/debug machines)

2.3 Operations for which Logical Domains can be used

C120-E534-15EN 2-3


Application performance on Logical Domains depend on the Control Domain. Performance overhead related to CPU and memory is small, because the Control Domain little interfere with CPU and memory in Guest Domains. But, if you employ virtual I/O, you should take account into a performance overhead. Typical applications applicable to LDoms are the followings.

• Web/Application servers. A software with a redundancy provided by dedicated middleware functions like load balance.

• Middleware Agent and other applications. A software which can be restarted properly from a failure.

• Development machines. A usage does not require a high availability or high performance.

Figure 2.6 Example of configuration for development and debug purposes


2-6 C120-E534-15EN

2.4 Logical Domains Performance

• There are almost no overheads related to CPU/memory resource.

• Please allocate units of cores to the Control Domain/Guest Domain for the purpose of minimizing CPU overhead influence.

• The performance of the virtual I/O may be degraded compared to the performance of direct I/O, which handles I/O directly. This is because Control or I/O Domains intermediate such data transfer. In case that high I/O load is expected, I/O, Fujitsu recommends a preliminary performance test. Please contact the relevant sales in your regions if a device for advanced verification is required.

• The CPU load of the Control Domain and/or I/O Domain increases when the virtual network device (vnet) is used in the Guest Domain.

• Because accesses to one of network card is done on one CPU thread in the Control or I/O Domains, please use the same number of network cards as that of the number of vnets and allocate the same number of CPU threads to the Control Domain.

C120-E534-15EN 3-1

Chapter 3 Logical Domains Configuration Design

3.1 Notices for Logical Domains configuration

3.1.1 Configurations

• For Logical Domains Manager Software, an installation server is required to install to the Guest Domain.(Logical Domains1.0.2)

3.4 Notes for I/O Building

C120-E534-15EN 3-5

3.4 Notes for I/O Building

Notes for I/O building in the Logical Domains environment are explained in this section. The following domain can be configured in SPARC Enterprise T Series.

• Control Domain • I/O domain • Guest Domain

If your computer operation requires high disk throughput the Guest Domain (such as database access operation), please construct a I/O domain that has direct access to disk devices. Applications or middleware's accessing disks frequently should be run in the I/O domain. When a large amount of network access occurs in the Guest Domain (For instance, file transfer), please configure the I/O domain with direct access to a network card (such as Gigabit Ethernet card). If your application or middleware uses a large amount of network access, please try to run it in the I/O domain.

• Create one Control Domain. You should not perform any business application on it. • In this example, the Control Domain and Business Server2 (Guest Domain) are the I/O domain and

service domain. They can be configured not to have the role of the service domain. • In this example, I/Os in Business Server1 and 3 (Guest Domains) are configured as virtual I/Os. • In SPARC Enterprise T Series, the numbers of I/O domains are different by models.


3-6 C120-E534-15EN

3.4.1 Allocation of disk device • Please use Direct I/O to connect internal disks to the Control Domain. • Please use Direct I/O or PCI(e) direct I/O to connect external disks (file unit devices, disk array

devices) to the Control Domain or I/O domains. • Fujitsu recommends to use Direct I/O or PCI(e) direct I/O in I/O Domains for data and system disks.. • Please use Direct I/O to allocate NIC to the Control Domain. • To Guest Domains, use virtual disk and virtual network which allow to connect physical disks and

networks through the Control Domain or I/O Domains. Please notice Direct I/O or PCI(e) direct I/O is not available in Guest Domains.

• Virtual Disk can allocate the following the disk types. - Solaris VM volumes - Physical devices

Internal disks - File Unit connected with SCSI card - File Unit connected with SAS card - ETERNUS 2000/3000/4000/6000/8000 series connected with 8GFC card

- Use disk mirroring software such as PRIMECLUSTER GDS, Solaris Volume Manager, and ZFS to mirror internal disks and external file unit devices. Fujitsu recommends using other disks for Virtual Disks from disks in Control Domain or I/O Domains. If you use the same disk, please separate partitions. We recommend that different disks be allocated for each domain.

- Do not delete a virtual I/O device. For more information, please see "Chapter 7 Using Virtual Disks" in "Oracle VM Server for SPARC 2.2 Administration Guide", provided by Oracle Corporation. http://docs.oracle.com/cd/E35434_01/html/E23807/usingvirtualdiskswithldoms.html

3.4.2 Notes for RAID software

• RAID software can be installed on the Control Domain and I/O domains to which Direct I/O is connected. However, RAID functionality is not available in Guest Domains.

• Solaris volume manager (hereinafter referred to as Solaris VM) is also available in the Control Domain where Direct I/O is connected or I/O domain.

• The disk that implements mirroring in the Control Domain or I/O domain can be allocated to another domain as the virtual disk.

• For using the GDS operation management view of PRIMECLUSTER GDS, change the security settings of Solaris Security Toolkit (SST) in order to access the system from the web browser of the client PC.

3.4.3 Notes on the connection of the disk array device (ETERNUS, Sun STK)

• Devices with multi-path configuration can be used with the ETMPD (ETERNUS multi-path driver), and MPxIO in the Control Domain or I/O domain. Moreover, these disks can be allocated to the virtual disk. Note) ETERNUS multipath driver (ETMPD) is not supported by Oracle Solaris 11.

Fujitsu recommends using MPxIO with Oracle Solaris 11.

3.6 Notes for Network building

C120-E534-15EN 3-15


Notes for the network building in the Logical Domains environments are explained in this section.

3.6.1 Allocation of the virtual switch (vsw) or virtual network device (vnet)

• Fujitsu recommends to allocate one vsw service for NIC and to allocate the VSW to one vnet according to the following configuration example. When sharing one NIC between multiple Guest Domain through corresponding vnet and vsw, the upper limit of the throughput sum for all VNETs is limited by throughput of the NIC.

[Configuration example]

Figure 3.9 Allocation of the virtual switch (vsw) or virtual network device (vnet)

• DO NOT allocate 32 or more vnet for one vsw service. If the VNET set-up is over the limit, the load for the Control Domain may become very high, leading to a suspension of system operations.

• The VLAN for vnet is available. • The Jumbo frame of vnet and vsw is available from Logical Domains1.2 and following releases.


3-16 C120-E534-15EN

3.6.2 Multi-path and NIC redundant configuration

• In the following conditions, the NIC redundant configuration will be available when the Link Aggregation function in the standard Solaris 10 OS or later used with Logical Domains. - The NIC driver that supports Link Aggregation of the Solaris 10 OS standard should correspond

to GLDv3. - Kernel Patch 127127-11 must be applied to the Control Domain. - Please notice that link aggregation can be done only in Control Domain. In the Guest Domain,

vnet cannot be brought together in aggr. [Configuration example]

Figure 3.10 Link Aggregation configuration with Control Domain

• The NIC redundant configuration will be available when the IP network multi-path (IPMP) function

in the standard Solaris 10 OS or later used with Logical Domains. - Notes on the IPMP configuration in the Guest Domain.

The method of the fault detection that you can use is a fault detection by the test signal and a fault detection by the link state monitoring.

*) Fault detection by monitoring the link state is not supported by Logical Domains 1.2 or later. The Control Domain and Guest Domains requires Solaris 10 10/09 OS or later. For more information, please see "Oracle VM Server for SPARC 2.2 Administration Guide", provided by Oracle Corporation.

4.2 Building Flow

This section describes the steps for building Logical Domains system. 1) Determine the Logical Domains configuration. 2) Prepare the Logical Domains configuration scripts. 3) Define the Guest Domain Administrative Users. 4) Prepare the Files for the Virtual Disks. 5) Build the Control Domain. 6) Build the Guest Domain. 7) Retain the Logical Domains Configuration Information. 8) Install the Guest Domain. 9) Configuration of domain dependency relationships. This section explains 1) Determin the Logical Domains Configuration and 2) Prepare the Logical Domains configuration scripts.

4.2.1 Determining the Logical Domains configuration

This section describes configurations for the domains, the virtual services and the hardware resources allocated to each domain.

4.2.1.1 Logical Domains configuration name

The system controller can store up to eight Logical Domains configuration (config). The stored configurations can be switched by powering on or resetting the system after designating the configuration for future use. The configuration is specified as 'initial' in this document.

4.2.1.2 Domain names

Fujitsu recommends that the number of the domain operated in Logical Domains be less than or equal to the number of CPU cores. In this document, we take the case of SPARC Enterprise T5120/5220 and the domain structure is configured with the primary domain, ldom1, ldom2, and ldom3.

4.2.1.3 The virtual CPU allocation

The number of virtual CPU is expressed in units of threads or cores. It is recommended that you should set a multiple of the number of threads per CPU core for the number of virtual CPUs. When creating the Control Domain, set the number of virtual CPUs after changing it to the delayed reconfiguration mode. Change the Control Domain to the delayed reconfiguration mode by using the following command. # ldm start-reconf primary

After creating the Control Domain, the number of virtual CPUs of the Control Domain can be changed dynamically. For the details, please refer to each related manual of Oracle listed in "Reference Manuals" in "Preface" of this document.

4.2 Building Flow

C120-E534-15EN 4-7

4.2.1.4 The Memory allocation

Allocate 4MB of memory to each domain. Memory reserved for the communication with hypervisor cannot be allocated. Please check an available size for the allocation from the output result of the following command. primary# ldm list-devices -a

Note) The size of memory reserved for the communication with hypervisor may be varied by machine types or the firmware versions.

It is recommended that the total size of memory you will allocate to the Control Domain and the above-mentioned memory you cannot allocate should be a multiple of 256 MB when you are going to allocate memory to the Control Domain. It is recommended that the size of memory to be allocated to a Guest Domain should be a multiple of 256 MB. When you change the memory allocation to each Guest Domain dynamically, specify a multiple of 256 MB. For more information, please read each related manual of Oracle described in "Reference Manuals" of "Preface" of this document.

4.2.1.5 The virtual disk service

The virtual disk service is configured using the following resources.

The virtual disk server (vdiskserver)

The virtual server device (vdiskserverdevice)

The virtual disk (vdisk) In this document, the virtual disk server (primary-vds0) can operate on the Control Domain, and the three virtual disk devices, vol1, vol2 and vol3, are allocated to ldom1, ldom2, and ldom3, as virtual disks (vdisk0).

You can specify a general file in the UFS file system as a virtual disk device. In this section, allocate the file on the following directory structure as the virtual disk server device.


4-8 C120-E534-15EN

4.2.1.6 The virtual switch service

The virtual switch service is configured using the following resources.

The virtual switch (vswitch)

The virtual network device (vnet)

The network adapter (net-dev) The virtual switch service (primary-vsw0, primary-vsw1, primary-vsw2, and primary-vsw3) can operate on the Control Domain, and the network adapter (e1000g0) is used by all domains. The virtual switch is allocated for each of ldom1, ldom2, and lodm3 to use e1000g1, e1000g2 and e1000g3 as the dedicated network adapter of the virtual network device (vnet1) In the following example, the name of the driver (e1000g) is the standard LAN port of SPARC Enterprise T5120/T5220. For the driver name of a standard LAN port of each machine model, please see "Notes on SPARC Enterprise T Series" in "SPARC Enterprise Oracle VM Server for SPARC Important Information". http://www.fujitsu.com/global/services/computing/server/sparcenterprise/products/software/ldoms/

4.2.1.7 Distributing device service of the virtual console terminal

The Guest Domain console is connected with the virtual console (vcons), which is provided by the distributing device service of the virtual console terminal (vconscon), and the virtual network terminal server (vntsd). The distributing device service of the virtual console terminal allocates dedicated port numbers that do not overlap with those of the other network services for the virtual console of the Guest Domain. Automatic assignment of port numbers is available. However, in this case, the port numbers of the virtual console are changed by the binding/unbinding of the Guest Domain resources. The virtual network terminal server provides a function for connecting via the telnet command, to the virtual console of the Guest Domain to which a port number is allocated by the distributing device service of the virtual console. In this document, the dedicated port numbers for 5001 to 5003 are allocated for each virtual console of ldom1, ldom2 and ldom3.

4.2.1.8 Creating the allocation sheet for hardware resources

Creating allocation sheet for the hardware resources below makes it easy for checking the configuration. Table 4.1 Hardware resource allocation

Configuration name (CONFIG)

Initial Remarks

Domain name (DOMAIN)

primary ldom1 ldom2 ldom3 This is the name used for control by Logical Domains Manager. It is not linked to the host name or node name.

Virtual CPU numbers (VCPU)

24 (3 core X 8 thread)

16 8 8 Specify a multiple of the number of threads per CPU core. With extensibility in mind, it is recommended that you should prepare a virtual CPU that is not allocated to any domains and set the virtual CPU by specifying the number of cores for Primary. Also, it is recommended that you should not set a virtual CPU by specifying the number of cores because you cannot add VCPU exceeding max-cores to any domains other than the Control Domain.

Memory (MEM)

3968M 2048M 1024M 1024M Exclude the memory size allocated to firmware. When 1024MB is allocated, enter [1024M], and when allocating 4GB, enter [4G]. Allocate memory by 4GB in Oracle VM Server for SPARC 2.0 or newer. (It is recommended that memory should be allocated by 256MB.) For the details on memory, please refer to each related manuals of Oracle described in "Reference Manuals" of "Preface" in this document.

Cryptographic device *(MAU)

0 0 0 0 Specify the MAU unit number. In this construction procedure zero is set. You cannot allocate the MAU beyond the number of CPU cores.

Virtual network device 0(VNET0)

vsw0 vsw0 vsw0 Specify the virtual switch service for connecting to virtual network device 0.


vsw1 vsw2 vsw3 Specify the virtual switch service for connecting to virtual network device 1.

Virtual disk 0 (VDISK0)

vol1 vol2 vol3 Specify the virtual disk server device for allocating to virtual disk 0.

Virtual console (VCONS)

5001 5002 5003 Specify the port number for allocating to the virtual console.

4.2.2 Preparing the Logical Domains configuration script

The Control Domain configuration script and the Guest Domain configuration script are created with the allocation sheet of the hardware resources that were created in the Logical Domains configuration. Save the created script in the directory for the Logical Domains configuration script (/LDoms/Scripts/) for making the script operable as required.

4.2.2.1 Creation of the Control Domain configuration scripts The following is an example of the Control Domain configuration script. Set the values of the allocation sheet of the hardware resources to the shell variables (CONFIG, VCPU, MAU, MEM). This script is stored in the /LDoms/Scripts/ directory of the Control Domain under the name primary.sh. #!/bin/sh # Control domain configuration script (for 4 domains) CONFIG=initial # Configuration name to store in the system controller VCPU=3 # Virtual CPU numbers to allocate to the Control Domain (*1) MAU=0 # MAU numbers to allocate to the Control Domain MEM=3968M # Memory to allocate to the Control Domain (K:KB,M:MB,G:GB) ldm start-reconf primary ldm set-mau $MAU primary ldm set-vcpu -c $VCPU primary ldm set-memory $MEM primary # Define the virtual disk server. ldm add-vdiskserver primary-vds0 primary # Define the virtual disk server device and specify the entity. ldm add-vdiskserverdevice /LDoms/Vol1/vdisk0.img vol1@primary-vds0 ldm add-vdiskserverdevice /LDoms/Vol2/vdisk0.img vol2@primary-vds0 ldm add-vdiskserverdevice /LDoms/Vol3/vdisk0.img vol3@primary-vds0 # Define the virtual switch service and specify the network adapter.

4.2.3 Defining the Guest Domain Administrative Users

Only the root users of the Control Domain can use the ldm command by default. System operation by only the root user or sharing of the root user's password with several users is not recommended on security grounds. If the users who control the only Guest Domain are allowed to use the ldm command, system control by root users or the password sharing of root users is not required. The following are permitted by installing Logical Domains Manager.

solaris.ldoms.read: the sub commands beginning with ldm list or ldm list- are available.

solaris.ldoms.write: all of the ldm sub commands are available. The following procedure indicates the steps from creating a role that has Logical Domains control authority through permissions added by Logical Domains Manager, up to the phase where the administrative user of the Guest Domain that granted the role is enabled to use the ldm command.

1) Define the ldom1opr that controls the Guest Domain ldom1. primary# groupadd ldomadm primary# mkdir -p /LDoms/ldom1opr primary# useradd -g ldomadm -d /LDoms/ldom1opr ldom1opr primary# passwd ldom1opr

New password:<Initinal password of ldom1opr>

Re-entry a new password: <the initial password of ldom1opr>

passwd: The password of ldom1opr is changed.

2) Change the owner of the home directory and .profile file. primary# chown ldom1opr:ldomadm /LDoms/ldom1opr

primary# chown ldom1opr:ldomadm /LDoms/ldom1opr/.profile

3) Define the role of the Guest Domain administration, ldomadm. primary# roleadd -A solaris.ldoms.write ldomadm

primary# passwd ldomadm

A new password: <the password of ldomadm>

Re-entry a new password: <the password of ldomadm>

passwd: The password of ldomadm is changed.

4) Allocate the role of ldomadm to the ldom1opr users. primary# usermod -R ldomadm ldom1opr

5) Check whether the role is available. Allocate the ldomadm role to all of the users administrating the other domains.

primary# su - ldom1opr primary# ldm list-domain Authorization failed primary# su ldomadm Password: <the password of ldomadm>

$ ldm list-domain

4.2.7 Retaining the Logical Domains Configuration Information

Logical Domains Manager 1.2 Patch 142840-04 or newer needs to be applied to get the configuration information (For Logical Domains 1.2). After applying 142840-04 or newer, please get the configuration information. The hypervisor reads the Logical Domains configuration stored in EEPROM at the time of power activation. The Logical Domains configuration may be lost as a result of a failure of hardware, which includes EEPROM, such as a motherboard. The Logical Domains Manager starts the Guest Domain by referring to the Logical Domains configuration which has been stored on the disk (/var/opt/SUNWldm/). If this disk cannot be accessed, the Guest Domain will not start the Guest Domain. The following corrective actions are recommended for these conditions.

• Save of the building script. Save the building script in a certain location (/LDoms/Scripts/ in this document) so that the latest Control Domain building script (primary.sh in this document) or Guest Domain building script (ldom?.sh in this document) can be executed as required, and so that the Logical Domains environment can be rebuilt.

• Collection/Save of the Control/Guest Domain configuration information. The outputs of ldm list-constraints -x when used for the input of ldm init-system -r -i [file-name], can rebuild the collected Control Domain. Also, the outputs of ldm list-constraints -x [domain-name] when used for the input of ldm add-domain -i [file-name], can rebuild the collected Guest Domain. Collect the configuration information of the Control/Guest Domain whenever the configuration is changed and save it in a certain location (/LDoms/Domains/ in this document).

• Getting and saving of the configuration information saved automatically. If you change the configuration information on Logical Domains 1.2, the change is reflected also to the auto-saved configuration information. You can use ldm list-spconfig -r to check the list of the configuration information saved automatically. Please save the auto-saved configuration information on the disk (/var/opt/SUNWldm/autosave-[autosave-name(*)]/) into the same location (/LDoms/Domains/ in this chapter) as the configuration information saved in " Collection/Save of the Guest Domain configuration information ".

*) autosave-name: The name of the auto-saved configuration information in the Control Domain. Be sure to login as root user to execute the following procedure. The following is an example of a method for saving. In this section, the auto-saved configuration information "webDB-config" is saved as "autosave-webDB-config.<date_time>.tar". 1) Check the name of the auto-saved configuration information.

primary# ldm list-spconfig -r

webDB-config

2) Save the auto-saved directory.

primary# cd /var/opt/SUNWldm

primary# tar -cvf /LDoms/Domains/autosave-webDB-config.`date +%y%m%d%H%M%S`.tar autosave-webDB-config

• Save of the information to external media. Copy the information in the CD-R, DVD-R, tapes or file servers to be prepared in case they are lost from the disk.

4.2.8 Installing the Guest Domain

This section describes an example of the installation procedure for of Oracle Solaris10.

The OS installation in Guest Domain is executed using the network installation method as well as the standard OS. Fujitsu recommends preparing one installation server. While Control Domain can be used as an installation server, additional setting is required - the cancellation of the SST security configuration and the setting for virtual network communication between the Control Domain and Guest Domain are required.

Note) It is advisable to confirm license policy for Operating Systems in Domains. Different versions of Operating Systems may require different licenses.

4.2.8.1 Making the settings to the installed server

1) Check the MAC address (Ethernet) of the Guest Domain (ldom1 in the following example). (Operation of Control Domain)

primary# ldm list-domain -l ldom1 <Enter>

4.2.9 Configuration of domain dependency relationships

Dependency relationships between domains can be configured. For more information, please see "Chapter 12 Performing Other Administration Tasks" in "Oracle VM Server for SPARC 2.2 Administration Guide", provided by Oracle Corporation.

http://docs.oracle.com/cd/E35434_01/html/E23807/otherinformationandtasks.html

4.2.9.1 Configuration of domain dependency relationships

Inter-domain dependencies can be configured on or after the domain creation. Fujitsu recommends that domain dependencies should be configured after domains are created. 1) Specify the master domain (ldom1) for the slave domain (ldom2). * primary# ldm set-domain master=ldom1 ldom2 <Enter>

2) Define failure policies (such as panic) for the master domain (ldom1). primary# ldm set-domain failure-policy=panic ldom1 <Enter>

3) Create configuration script to configure dependency relationships. ldm set-domain master=ldom1 ldom2

ldm set-domain failure-policy=panic ldom1

Note) Each slave domain can specify up to four master domains.

DO NOT set mutual dependency where two domains are defined dependent each other. When a master domain stops, a slave domain that has dependency relationships behaves according to the master domain's failure policy. The failure policy takes an action against the slave domain when the master domain stops. The status of master domain's stop means halts/reboots/reset/panic of the domain. Preparing a configuration script to define dependency relationships makes the recovery after maintenance easy.

4.2.9.2 Cancellation of domains dependency relationships

You need to cancel dependency relationships before domains maintenance. If a domain is stopped or rebooted without cancellation of the dependency relationships, its slave domains are affected. The following describes how to cancel domain dependencies. 1) Cancel the master domain of the slave domain (ldom2).

By specifying nothing for the master parameter, domain dependency relationships can be cancelled. primary# ldm set-domain master=ldom2 <Enter>

2) Create the configuration script to cancel the dependency relationships. ldm set-domain master=ldom2

Note) For easier operations before dependency cancellation, you had better create relevant configuration script beforehand.

Chapter 5 Building Procedure (Example 2) This chapter describes how to configure the Logical Domains environment of the I/O domain.

5.1 I/O Domains On SPARC Enterprise T Series, by dividing PCI Express leaf, you can configure domains (I/O domains) that are allowed to access I/O directly besides the Control Domain. You can occupy and use resources of I/O by using these domains as Guest Domains.

5.2 Building Procedure This section describes the procedure of building Logical Domains, and determination of Logical Domains configuration that you can make before starting the configuration, and preparation of Logical Domains system configuration script. If you create the Control Domain, or I/O domain on disks connected by Fujitsu option, you must have an installation server. The following describes the steps of building Logical Domains system.

1) Firmware 2) Determining the Logical Domains configuration 3) Preparing the Logical Domains configuration scripts 4) Building an Installation Server 5) Defining the Guest Domain Administrative Users 6) Preparing the Files for the Virtual Disks 7) Dividing PCI devices 8) Building the Control Domain 9) Building the I/O domain 10) Building the Guest Domain 11) Retaining the Logical Domains Configuration Information 12) Installing the Guest Domain 13) Saving the Logical Domains setting

5.2.1 Firmware For confirming firmware version numbers, you must visit different methods for ALOM and ILOM.

5.2 Building Procedure

C120-E534-15EN 5-3

5.2.2 Determining the Logical Domains configuration

The domains to be constructed, the virtual services and the hardware resources allocated to each domain are configured.

5.2.2.1 Logical Domains configuration name

The configuration is specified as 'split-io', 'initial', 'initial-io', or 'operation' in this document.

5.2.2.2 Domain names

Fujitsu recommends that the number of the domain operated in Logical Domains be less than or equal to the number of CPU cores. In this document, four domains are configured as shown below. Control Domain : primary I/O Domain : iodom Guest Domain : ldom1, ldom2

5.2.2.3 The virtual CPU allocation

The number of virtual CPUs can be specified by the number of threads or cores. It is recommended that you should set a multiple of the number of threads per CPU core for the number of virtual CPUs. When creating the Control Domain, set the number of virtual CPUs after changing it to the delayed reconfiguration mode. Change the Control Domain to the delayed reconfiguration mode by using the following command. # ldm start-reconf primary

After creating the Control Domain, the number of virtual CPUs of the Control Domain can be changed dynamically. For details, refer to each related manual of Oracle listed in "Reference Manuals" in "Preface" of this document.

5.2.2.4 The Memory allocation

Allocate 4MB of memory to each domain. Memory reserved for the communication with hypervisor cannot be allocated. Please check an available size for the allocation from the output result of the following command. primary# ldm list-devices -a

* The size of memory reserved for the communication with hypervisor may be various by machine type or the firmware version.

It is recommended that the total size of memory you will allocate to the Control Domain and the above-mentioned memory you cannot allocate should be a multiple of 256 MB when you are going to allocate memory to the Control Domain. It is recommended that the size of memory to be allocated to a Guest Domain should be a multiple of 256 MB. When you change the memory allocation to each Guest Domain dynamically, specify a multiple of 256 MB. For more information, please read each related manual of Oracle described in "Reference Manuals" of "Preface" of this document.


5-4 C120-E534-15EN

5.2.2.5 The virtual disk service

In this document, the virtual disk server (primary-vds0) can operate on the Control Domain only, and the two virtual disk devices, vol1 and vol2, are allocated to ldom1 and ldom2, respectively as virtual disks (vdisk0).

You can specify a general file in the UFS file system as a virtual disk device. You can allocate the file on the following directory structure as the virtual disk server device.

5.2.2.6 The virtual switch service

The virtual switch service (primary-vsw0, primary-vsw1) can operate on the Control Domain, and the network adapter (fjgi0) is used by all domains. The virtual switch is allocated for each of ldom1, and ldom2 to function as the dedicated network adapter of the virtual network device (vnet1). I/O domain will be connected with the Control Domain and Guest Domain via network switch.

5.2.2.7 Distributing device service of the virtual console terminal

In this document, the dedicated port numbers from 5000 to 5002 are allocated for each virtual console of iodom, ldom1, and ldom2.


C120-E534-15EN 5-5

5.2.2.8 Creating the allocation sheet for hardware resources

The following allocation sheet for the hardware resources is created. Table 5.1 Hardware resource allocation

Configuration scripts for creation of Control or Guest Domain are created with the allocation sheet of the hardware resources that were created in the Logical Domains configuration. Save the created script in the directory for the Logical Domains configuration script (/LDoms/Scripts/) to make the script operable as required.

5.2.3.1 Creation of the Control Domain configuration scripts

The following is an example of the Control Domain configuration script. Set the values of the allocation sheet of the hardware resources to the shell variables (CONFIG, VCPU, MAU, MEM). This script is stored in the /LDoms/Scripts/ directory of the Control Domain under the name of primary.sh. #!/bin/sh

# Control Domain configuration script (for 4 domains)

CONFIG=initial # Configuration name to store in the system controller

VCPU=3 # The number of cores (virtual CPUs) to be allocated to the Control Domain (*1)

MAU=0 # MAU numbers to allocat to the Control Domain

MEM=3968M # Memory to allocate to the Control Domain (K:KB,M:MB,G:GB)

ldm start-reconf primary

ldm set-mau $MAU primary

ldm set-vcpu $VCPU -c primary

ldm set-memory $MEM primary

# Define the virtual disk server.

ldm add-vdiskserver primary-vds0 primary

# Define the virtual disk server device and specify the entity.

ldm add-vdiskserverdevice /LDoms/Vol1/vdisk0.img vol1@primary-vds0

ldm add-vdiskserverdevice /LDoms/Vol2/vdisk0.img vol2@primary-vds0

# Define the virtual switch service and specify the network adapter. (*2)

ldm add-vswitch net-dev=fjgi0 primary-vsw0 primary

ldm add-vswitch net-dev=fjgi1 primary-vsw1 primary

# Specify the distributing device service of the virtual console terminal and the port range to allocate.

ldm add-vconscon port-range=5000-5100 primary-vcc0 primary

eeprom auto-boot\?=false

# Save the configuration in the system controller.

ldm add-spconfig $CONFIG

# After executing this script, the power-off, reclosing or reset is required.

*1) For the Control Domain, please set virtual CPUs by specifying the number of cores. *2) If you configure the I/O domain, please specify the driver name of LAN card added to PCIe Slot1 or Slot2

(or Slot3 if your machine is T5140).

5.2.5 Defining the Guest Domain Administrative Users

Only the root users of the Control Domain can use the ldm command by default. System operation by only the root user or sharing of the root user's password with several users is not recommended on security grounds. If the users who control the only Guest Domain are allowed to use the ldm command, system control by root users or the password sharing of root users is not required. The following are permitted by installing Logical Domains Manager.

• solaris.ldoms.read: the sub commands beginning with ldm list or ldm list- are available.

• solaris.ldoms.write: all of the ldm sub commands are available.

The following procedure indicates the steps from creating a role that has Logical Domains control authority through permissions added by Logical Domains Manager, up to the phase where the administrative user of the Guest Domain that granted the role is enabled to use the ldm command.

1) Define the ldom1opr that controls the Guest Domain ldom1. primary# groupadd ldomadm primary# mkdir -p /LDoms/ldom1opr primary# useradd -g ldomadm -d /LDoms/ldom1opr ldom1opr primary# passwd ldom1opr New password:<Initial password of ldom1opr>

Re-entry a new password: <the initial password of ldom1opr>

passwd: The password of ldom1opr is changed.

2) Change the owner of the home directory and .profile file. primary# chown ldom1opr:ldomadm /LDoms/ldom1opr

primary# chown ldom1opr:ldomadm /LDoms/ldom1opr/.profile

3) Define the role of the Guest Domain administration, ldomadm. primary# roleadd -A solaris.ldoms.write ldomadm

primary# passwd ldomadm

A new password: <the password of ldomadm>

Re-entry a new password: <the password of ldomadm>

passwd: The password of ldomadm is changed.

4) Allocate the role of ldomadm to the ldom1opr users. primary# usermod -R ldomadm ldom1opr

https://updatesite.jp.fujitsu.com/unix/en/download/driver/index.html


C120-E534-15EN 5-11

5) Check whether the role is available. Allocate the ldomadm role to all users who manage other domains.

primary# su - ldom1opr primary# ldm list-domain Authorization failed primary# su ldomadm Password: <the password of ldomadm> $ ldm list-domain ... NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv SP 64 8064M 0.1% 43m

$ exit

6) When the following is executed, only the subcommands beginning with ldm list or ldm list-, will be available. An error may occur if "solaris.jobs.users" is specified. When the error occurs, remove "solaris.jobs.users" before the execution.

primary# usermod -A

"solaris.device.cdrw,solaris.profmgr.read,solaris.jobs.users,solaris.mail.mailq,solaris.ldoms.read" ldom1opr

The following table indicates the relationship between the user's names/roles names in the definition or Control Domain and executable functions. Table 5.2 The ldm Subcommands and User Authorizations, role

5.2.11 Retaining the Logical Domains Configuration Information

Logical Domains Manager 1.2 Patch 142840-04 or newer needs to be applied to get the configuration information (For Logical Domains 1.2). After applying 142840-04 or newer, please get the configuration information. The hypervisor reads the Logical Domains configuration stored in EEPROM at the time of power activation. The Logical Domains configuration may be lost as a result of a failure of hardware which includes EEPROM, such as a motherboard. The Logical Domains Manager starts the Guest Domain by referring to the Logical Domains configuration which has been stored on the disk (/var/opt/SUNWldm/). If this disk cannot be accessed, the Guest Domain will not start the Guest Domain. The following corrective actions are recommended for these conditions.

• Save of the building script. Save the building script in a certain location (/LDoms/Scripts/ in this document) so that the latest Control Domain building script (primary.sh in this document) or Guest Domain building script (ldom?.sh in this document) can be executed as required, and so that the Logical Domains environment can be rebuilt.

• Collection/Save of the Control/Guest Domain configuration information. The outputs of ldm list-constraints -x when used for the input of ldm init-system -r -i [file-name], can rebuild the collected Control Domain. Also, the outputs of ldm list-constraints -x [domain-name] when used for the input of ldm add-domain -i [file-name], can rebuild the collected Guest Domain. Collect the configuration information of the Control/Guest Domain whenever the configuration is changed and save it in a certain location (/LDoms/Domains/ in this document).

• Getting and saving of the configuration information saved automatically. If you change the configuration information on Logical Domains 1.2, the change is reflected also to the auto-saved configuration information. You can use "ldm list-spconfig -r" to check the list of the configuration information saved automatically. Please save the auto-saved configuration information on the disk (/var/opt/SUNWldm/autosave-[autosave-name(*)]/) into the same location (/LDoms/Domains/ in this chapter) as the configuration information saved in "Collection/Save of the Guest Domain configuration information". *autosave-name: The name of the auto-saved configuration information in the Control Domain

Be sure to login as root user to execute the following procedure. The following is an example of a method for saving. In this section, the auto-saved configuration information "webDB-config" is saved as "autosave-webDB-config.<date_time>.tar". 1) Check the name of the auto-saved configuration information. primary# ldm list-spconfig -r webDB-config

2) Save the auto-saved directory. primary# cd /var/opt/SUNWldm primary# tar -cvf /LDoms/Domains/autosave-webDB-config.`date +%y%m%d%H%M%S`.tar autosave-webDB-config

- Save of the information to external media. Copy the information in the CD-R, DVD-R, tapes or file servers to be prepared in case they are lost from the disk.

The OS installation of the Guest Domain is executed using the network installation method as well as the standard OS. Fujitsu recommends to prepare another chassis for the installation server. While Control Domain can be used as installation server, additional setting is required. The cancellation of the SST security configuration and the setting for virtual network communication between the Control Domain and Guest Domain are required.

Note) It is advisable to confirm license policy for Operating Systems in Domains. Different versions of Operating Systems may require different licenses..

5.2.12.1 Making the settings to the installed server

1) Check the MAC address (Ethernet) of the Guest Domain (ldom1 in the following example). (Operation of Control Domain) DO NOT USE the result displayed by the banner command of the Guest Domain OBP.

primary# ldm list-domain -l ldom1 <Enter> : NETWORK NAME SERVICE DEVICE MAC vnet0 primary-vsw0@primary network@0 <MAC address of the guest domain>


installserver# vi /etc/ethers <Enter> (Add the following) <MAC address of the guest domain> ldom1 ... installserver# vi /etc/hosts <Enter> (Add the following) 192.168.1.101 ldom1 ...

3) Set the installation client. (Operation of installed server) Remarks) Create the Solaris install image of the installation server in advance.

installserver# cd <path to the Solaris image>/Solaris_10/Tools <Enter> installserver# ./add_install_client ldom1 sun4v <Enter>

4) Confirm the setting. (Operation of installed server) installserver# cat /etc/bootparams <Enter> ldom1 root=192.168.1.100:/export/image/solaris10_9_10/Solaris_10/Tools/ Bootinstall=192.168.1.100:/export/image/solaris10_9_10/boottype=:in rootopts=:rsize=8192

5) Share the install image. (Operation of installed server) Remarks) It is not necessary to execute the command when sharing has already been done.

installserver# share -o ro,anon=0 /export/image <Enter>

7.4 Backing Up/Restoring the File System

Back up/restore the file system of the Guest Domain on each Guest Domain only for the virtual disks that were bound to the domain. Refer to the following documents for information on saving/restoring the file system.

• System Administration Guide: Devices and File Systems


The tape device cannot be allocated to the Guest Domain. Use the remote tape drive when backings up/restoring the virtual disks on the Guest Domain. Use the following procedure to use the remote tape drive.

1) Add the Guest Domain entry on the /etc/inet/hosts file or the name service of the remote host (remotehost) to which the tape device is connected.

2) Add the remote host entry on the /etc/inet/hosts file or the name service of the Guest Domain.

3) Make the rlogin service of the remote host operational.

4) Create the rhosts file ($HOME/.rhosts) in the home directory of the root user in the remote host and then add the host name of the Guest Domain.

The following is an example of the configuration of the rhosts file of the root user.

remotehost# cat >> $HOME/.rhosts

ldom1

ldom2

ldom3

<Ctrl+d>

remotehost# chmod 0400 $HOME/.rhosts

The following is an example of using the remote tape drive.

ldom1# ufsdump 0ucf remotehost:/dev/rmt/0n /dev/rdsk/c0d0s0

ldom1# rsh remotehost mt -f /dev/rmt/0 rewind

ldom1# ufsrestore tf remotehost:/dev/rmt/0

Remarks) • DO NOT ACCESS the virtual disk entities that connect to the Guest Domain from the Control

Domain. Access to virtual disk entities, which is canceled for the consolidation to the Guest Domain from the Control Domain, is available. However, when the consolidated virtual disk entities are read or written from the Control Domain, disk errors or system hang-up may occur.

• When you need to access a virtual disk from Control Domain also connected to the Guest Domain, and unbind the Guest Domain.

• When restoring the virtual disk entity connected to the Guest Domain by using tasks including restoration of the Control Domain, a part of or all of the contents of the virtual disks of the Guest Domain may be lost. When the virtual disk entity connected to the Guest Domain, is restored by the Control Domain, restore the corresponding virtual disk on the Guest Domain by using the data saved from the Guest Domain.

7.7 Making Temporary Configuration Changes to Domains

C120-E534-15EN 7-19


This section explains a method for allocating hardware resources temporarily. For permanent allotment of hardware resources, Fujitsu recommends to remove the Guest Domain once and then executing the building script reflecting the configuration changes.

7.7.1 Adding/removing virtual CPUs

1) Check the virtual CPU numbers of each domain. primary# ldm list-domain <Enter>

NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv SP 8 4G 3.1% 1d 36m ldom1 active -n--- 5001 16 2G 34% 1m ldom2 active -n--- 5002 16 1G 34% 17h 48m ldom3 active -n--- 5003 24 4G 17% 17h 48m

2) Remove CPUs. (Remove the eight VCPUs of ldom3.)

primary# ldm remove-vcpu 8 ldom3 <Enter>

3) Add the CPUs. (Add the eight VCPUs to ldom1)

primary# ldm add-vcpu 8 ldom1 <Enter>

4) Check the virtual CPU numbers of each domain.


NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-cv SP 8 4G 0.2% 1d 1h 50m ldom1 active -n--- 5001 24 2G 33% 1h 15m ldom2 active -n--- 5002 16 1G 0.1% 19h 3m ldom3 active -n--- 5003 16 4G 0.1% 19h 3m

Remarks) • The CPU in Control Domain too can be added/removed dynamically. • The stop of the domain and the cancelation of the consolidation are required for adding and

removing the virtual CPU for the domain to which the encryption unit numbers (MAU) are allocated.

• When adding/removing the virtual CPU for the domain for which the drd daemon does not operate, it will not become enabled until the domain is rebooted.

7.7.2 Adding/removing memory

1) Check the amount of memory allocated to the domain

primary# ldm list-domain <Enter> NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 8 4G 3.1% 1d 36m ldom1 active -n---- 5001 16 2G 34% 1m ldom2 active -n---- 5002 16 1G 34% 17h 48m ldom3 active -n---- 5003 24 4G 17% 17h 48m


7-20 C120-E534-15EN

2) Remove the domain memory. (Remove the 1GB memory of ldom3.) primary# ldm remove-memory 1G ldom3 <Enter>

3) Add the domain memory. (Add the 1GB memory to ldom1.) primary# ldm add-memory 1G ldom1 <Enter>

4) Check the memory amount of the domain. primary# ldm list-domain <Enter> NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv SP 8 4G 3.1% 1d 36m ldom1 active -n--- 5000 16 3G 34% 1m ldom2 active -n--- 5001 16 1G 34% 17h 48m ldom3 active -n--- 5002 24 3G 17% 17h 48m

In the same way, memory of the cotrol domain can be added or removed dynamically.

Adding or removing 256MB memory is possible.

For the details on memory, please refer to each related manuals of Oracle described in "Reference Manuals" of "Preface" in this document.

When you add or remove memory to/from a domain in which the drd daemon does not run e.g. a domain during installation, the addition or removal does not become effective until the domain is rebooted.

7.7.5 Modification of OBP variables, device-alias, time etc.

If you modified OBP variables, or device-alias, time etc. in the Control Domain, the modification does not become effective at the next power on. Before powering off the machine, the modification needs to be reflected to the configuration information. Also it is recommended that you reflect it in configuration script of the Control Domain. When the state of Guest Domain is changed, it is necessary to reflect it in configuration information. (But, due to the fact that setting up of clock time cannot be supported by construction scripts, it is necessary to set up the clock time of a domain with the date(1) command, after binding it.)

Example) In case of temporary change primary# ldm add-spconfig temp`date +%m%d` primary# ldm list-spconfig factory-default

7.8 Collecting/Restoring the Configuration Information of the Control Domain

This section explains how to collect Control Domain configurations and restore restore them. When you restore the configuration information of the Control Domain, you need to change the state of the Control Domain to the factory-default and also remove the Guest Domains.

7.8.1 Collecting the configuration information of the Control Domain

To collect the configuration information, Logical Domains Manager 2.0 or later must be installed. The following describes how to collect the configuration information of the Control Domain (In this example, the configuration information of 'primary' is saved in /LDoms/Domains.)

primary# ldm list-constraints -x primary > /LDoms/Domains/primary.xml <Enter>

- An environment setting file is created in xml format. - Please execute the above whenever you change the configuration. - Please save the replication into DVD-R, tape or a file server for avoiding loss of the configuration

information data from a disk. Also, For removing the Guest Domains when the Control Domain is rebuilt, the configuration information of the Guest Domains must be collected. The detailed information on collecting the configuration information of the Guest Domains is seen in "7.9 Collecting/Restoring the configuration information of the Guest Domain".

7.8.2 Restoring the Control Domain

Using the configuration information, the configuration of the Control Domain changed temporarily can be returned to where its configuration information was collected. You need to change the Control Domain to the state of the factory-default. The detailed information is given in "7.12.2 Removing the Logical Domains configuration".

7.8.2.1 Removing the Guest Domains

An explanation about removal of the Guest Domain is given in "7.12.1 Removing the Guest Domain".

7.14 Saving/Restoring of the configuration information of the Control/Guest Domain

Logical Domains Manager 1.2 Patch 142840-04 or newer needs to be applied to save the configuration information. (For Logical Domains 1.2) In this section, a method for getting the configuration information of the Control/Guest Domain by using the auto-recovery function of configurations and for restoring the Control/Guest Domain by using it is explained.

7.14.1 Getting of the configuration information of the Control/Guest Domain

Get the auto-saved configuration information of a domain in the following method. (In this example, auto-saved information - "webDB-config" is saved in /LDoms/Domains/ as autosave-webDB-config.<date_time>.tar.) 1) Check the name of the auto-saved configuration information.

primary# ldm list-spconfig -r

webDB-config

2) Save the auto-saved directory. Be sure to login as root user to execute the following procedure.

primary# cd /var/opt/SUNWldm

primary# tar -cvf /LDoms/Domains/autosave-webDB-config.`date +%y%m%d%H%M%S`.tar autosave-webDB-config

*1) Execute the above procedure whenever you change the configuration. *2) Save a copy into DVD-R, tape or file server in case of loss of the configuration information on the

disk.

7.14.2 Restoring of the configuration information of the Control/Guest Domain

By using the auto-saved configuration information, the Control and Guest Domain can be returned to the configuration when you got the configuration information of them. (In this example, the auto-saved configuration information saved as autosave-webDB-config.<date_time>.tar in /LDoms/Domains/ is reflected as the configuration information of the name of "webDB-config".)

7.14.2.1 Removing of the Guest Domain

Regarding removal of the Guest Domain, please refer to "7.12.1 Removing the Guest Domain".

Chapter 8 Tasks Required to Replace Parts This chapter, will discuss about the chores on the customer's side at the time of replacement of SPARC Enterprise T5120/T5220/T5140/T5240/T5440 server components by a service engineer. After replacing the motherboard and BSP board and SCC module, the factory-default settings of the Logical Domains environment become effective. Observe the following procedures in the order given: "8.2 Stopping the System Before Replacing Parts" and "8.3 Building Logical Domains after Replacing Parts". Moreover, on SPARC T3 server and above, the Logical Domains configuration information is contained in the backup of ILOM configuration information. Please refer to manuals published by Oracle or please contact to below for the procedure of backing up/restoration of Logical Domains configuration information.


8.1 Parts Replacement Performed by the Service Engineer

Your service engineer must replace the parts in the device-deactivated state and check their operations which include the POST completion of the Control Domain.


Chapter 8 Tasks Required to Replace Parts

8-2 C120-E534-15EN

8.2 Stopping the System Before Replacing Parts

If the hardware failure occurs, and you execute the following parts replacement procedure, the Logical Domains environment must be deleted before starting the procedure. Stop the system first, and then perform the procedure by referring to "8.1 Parts replacement performed by the Service Engineer".

• Replacing the motherboard. (SPARC Enterprise T5120/T5220/T5140/T5240) • Replacing the BSP board. (SPARC Enterprise T5440)

*) Procedures in this section is necessary because of Logical Domains configuration stored in these components.

• Replacing SCC module. Even if SCC module is replaced, HostID and MAC address for the new SCC module cannot be reflected to LDoms environments. To reflect the changes, you are required to install and set up LDoms environment from scratch.

• Replacing parts in the factory default state. CMP module (SPARC Enterprise T5440) *) The server becomes factory default state during IBIS/POST after cpu is degenerated.

Figure 8.1 Task flow for stopping the system before replacing parts

8.3 Building Logical Domains after Replacing Parts

C120-E534-15EN 8-3

8.3 Building Logical Domains after Replacing Parts

Logical Domains must be rebuilt when the Logical Domains environment becomes the factory-default state. Refer to "Figure 8.2 Tasks flow for Building Logical Domains after Replacing Parts" for information on building the Logical Domains environment.

Notes) 1) The MAC addresses of the Guest Domain (HostID), virtual switch (vsw) or virtual network

(vnet), which are automatically allocated, may be changed. 2) The X part of the virtual switch (vswX), the virtual network (vnetX), and the virtual disk

(c0dXs0) may also be changed.

Appendix A. Instructions for Backup/Restoration of UFS file system

A.1 Notes on the descriptions of this instruction

Please notice that backup/restore for Guest Domain should be done only to virtual disks bound to a Domain in relevant Guest Domain. Refer to the following documents for information on saving/restoring the file system. • Solaris System Administration Guide: Devices and File Systems


The tape device cannot be allocated to the Guest Domain. Use the remote tape drive when backing up/restoring the virtual disks on the Guest Domain. After you complete backing up/restoring, return the setting to its original setting in case any security issues occur.

1) Add the Guest Domain entry on the /etc/inet/hosts file or the name service of the remote host (remotehost) to which the tape device is connected.

remotehost# echo "xxx.xxx.xxx.xxx ldom1" >> /etc/inet/hosts

2) Add the remote host entry on the /etc/inet/hosts file or the name service of the Guest Domain. ldom1# echo "xxx.xxx.xxx.yyy remotehost" >> /etc/inet/hosts

3) Make the rlogin service of the remote host operational. remotehost# cat >> $HOME/.rhosts

4) The following is an example of the configuration of the rhosts file of the root user. ldom1# ufsdump 0ucf remotehost:/dev/rmt/0n /dev/rdsk/c0d0s0


ldom1# ufsrestore tf remotehost:/dev/rmt/0


A.1 Notes on the descriptions of this instruction

A-2 C120-E534-15EN

The Control Domain can access virtual disk entities if they are released from binding a Domain. However, if the bound virtual disk entities are read or written from the Control Domain, disk errors or system hang-up sometimes occur in a Guest Domain. Therefore, DO NOT ACCESS the virtual disk entities that bound to the Guest Domain from the Control Domain. When accessing a virtual disk from the Control Domain bound to the Guest Domain, stop the Guest Domain and unbind it from the Control Domain. When restoring the virtual disk entity bound to the Guest Domain by using tasks such as restoration of the Control Domain, a part of or all of the contents of the virtual disks of the Guest Domain may be lost. When the virtual disk entity, which is connected to the Guest Domain, is restored by the Control Domain, restore the counterpart virtual disk on the Guest Domain by using the save data from the Guest Domain. Instructions on how to collect VTOC information

ldom1# prtvtoc /dev/rdsk/c#t#d#s2 > file

Appendix B Instructions for Backup/ Restoration of ZFS file system

C120-E534-15EN B-1

Appendix B. Instructions for Backup/ Restoration of ZFS file system

Here backup/restoration of ZFS file system is described.

Regarding general information on management of ZFS filesystem, please see the following manual.

• Solaris ZFS Administration Guide


You can install system volume on ZFS file system on Solaris OS 10/08 or later. The following describes examples of backup/restoration procedure of ZFS file system.

B.1 Notes on the descriptions of this instruction

• This instruction gives you useful information on how to backup/restore ZFS filesystem in the Control Domain or Guest Domains. Remarks) Although examples refers to the Control Domain (primary#), procedures is the same for

guest domains as well. • According to the environment, a local or remote tape drive, or disk is available for the backup

destination of ZFS filesystem. This document gives an example in which a local tape drive is used for the backup destination.

• In the following example of the setting, a remote tape drive is used. Return the setting to its original setting after performing backup or restoration to avoid security issues.

1) Add the entry of the target domain of backup or restoration to the /etc/inet/hosts file or name services of

the remote host (remotehost) where the tape drive is connected. remotehost# echo "xxx.xxx.xxx.xxx XXXXX" >> /etc/inet/hosts

2) Add the entry of the remote host to he /etc/inet/hosts file or name services of the target domain. primary# echo "xxx.xxx.xxx.yyy remotehost" >> /etc/inet/hosts

3) Enable the rlogin service of the remote host. remotehost# cat >> $HOME/.rhosts XXXXX <Ctrl+d>


4) The following example shows how to use the remote tape drive. primary# ufsdump 0ucf remotehost:/dev/rmt/0n /dev/rdsk/c0d0s0

primary# rsh remotehost mt -f /dev/rmt/0 rewind

primary# ufsrestore tf remotehost:/dev/rmt/0

C120-E534-15EN B-3

B.2 Backup of ZFS file system

Notes) • To backup ZFS file system, the patch 139555-08 or newer needs to be applied to the target domain for

the backup. Also notice Solaris 10 OS 5/09 or newer includes 139555-08. • Please note the following when your backup destination is a tape drive.

- A tape to backup data of the Control Domain should be different from one to backup data of each Guest Domain.

- Be sure to record which date is backed up and in what order. - The "zfs send" command does not support multi-volume. If one tape is not enough for backed up data,

backup the data to the tape with the tar command after backing up it to the disk or other storages. 1) Preparation

When you backup a filesystem in the Control Domain, stop all domains except the Control Domain and cancel the bind of resources.

In the following example, Guest Domains - ldom1, ldom2, and ldom3 exist.

Primary# ldm stop-domain ldom1






Collect information by zpool, disk, and filesystems beforehand, and backup them into another disk. A record of information collected with 'get all' should be kept because the record is useful for check after you restore the file system.

B.2 Backup of ZFS file system

B-4 C120-E534-15EN

2) Reboot the target domain of the backup in single user mode. ok boot -s

3) Saving System Information. Use the snapshot function to save system information. However, you do not have to save the dump and swap areas because they are work areas. Please remove unnecessary snapshots.

primary# zfs snapshot -r rpool@backup

primary# zfs destroy rpool/dump@backup

primary# zfs destroy rpool/swap@backup

primary# zfs snapshot -r ldomspool@backup


C120-E534-15EN B-5

4) Backup of System Information. Backup snapshots of each ZFS file system you saved in the step of 2). Specify a tape drive or another disk as backup destination. When you use a tape as backup destination, the tape for ZFS snapshot of the Control Domain should be different from the tape for ZFS snapshots of each Guest Domains.

primary# mt -f /dev/rmt/0 rewind

primary# zfs send -v rpool@backup > /dev/rmt/0cn

primary# zfs send -v rpool/ROOT@backup > /dev/rmt/0cn

primary# zfs send -vR rpool/ROOT/s10s_u6wos_07b@backup > /dev/rmt/0cn

primary# zfs send -v rpool/export@backup > /dev/rmt/0cn

primary# zfs send -v rpool/export/home@backup > /dev/rmt/0c

(Tape exchange)


primary# zfs send -v ldomspool@backup > /dev/rmt/0cn

primary# zfs send -v ldomspool/ldom2@backup > /dev/rmt/0c

B.3 Restoration of ZFS File System

B-6 C120-E534-15EN


Notes)

• If you use this procedure to restore ZFS filesystem, you need to boot the system in single user mode from the boot image where 139555-08 or newer is applied. If your OS is Solaris 10 OS 5/09 or newer, 139555-08 is included.

• Backup data used in this procedure must be data backed up in "B.2 Backup of ZFS filesystem".

• ZFS storage pool before the backup must have the same name as after the restoration. 1) Preparation of Restoration Destination System.

(1) Boot the system in single use mode from a network installation environment. *) You need to configure the network installation environment beforehand.

{0} ok boot net -s

(2) Create disk slice and disk label by using the format(1M) or fmthard(1M) command according to disk partition information you recorded beforehand.

primary# format

Or,

primary# fmthard -s primary-c0t2d0s2.map /dev/rdsk/c0t2d0s2

2) Restoration of System File. Restore system information backed up from a disk or external media such as a tape drive.

(1) Create a new storage pool to mount the disk where backuped files are stored.

primary# zpool create -fo altroot=/var/tmp/rpool -o cachefile=/etc/zfs/zpool.cache -o failmode=continue -m legacy rpool c0t2d0s0

(2) Restore disks composing 'rpool'.


primary# zfs receive -Fd rpool < /dev/rmt/0n




primary# zfs receive -Fd rpool < /dev/rmt/0


C120-E534-15EN B-7

(3) Create 'dump' and 'swap'. You need to create 'dump' and 'swap' individually because they are not backed up. Information of dump and swap collected in the preparation described in "3.Notes on backup of ZFS filesystem".

primary# zfs get all rpool/dump NAME PROPERTY VALUE SOURCE rpool/dump type volume - rpool/dump creation Tue Apr 7 18:13 2009 - rpool/dump used 1.00G - rpool/dump available 29.1G - rpool/dump referenced 1.00G - rpool/dump compressratio 1.00x - rpool/dump reservation none default rpool/dump volsize 1G - rpool/dump volblocksize 128K - rpool/dump checksum off local rpool/dump compression off local rpool/dump readonly off default rpool/dump shareiscsi off default rpool/dump copies 1 default rpool/dump refreservation none default

primary# zfs get all rpool/swap

Specify 'volsize' for the -V option of the 'create'.

primary# zfs create -o volblocksize=128k -V 1g rpool/dump primary# zfs create -o volblocksize=8k -V 2g rpool/swap


B-8 C120-E534-15EN

3) Create 'bootblock'.

primary# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t2d0s0

primary# zpool set bootfs=rpool/ROOT/s10s_u6wos_07b rpool

primary# zfs set canmount=noauto rpool/ROOT/s10s_u6wos_07b

primary# zfs set canmount=noauto rpool

primary# zfs set mountpoint=/rpool rpool

primary# zfs set mountpoint=/export rpool/export

primary# zfs set mountpoint=legacy rpool/ROOT

primary# zfs set canmount=on rpool

primary# zpool export rpool

4) Boot the system from rpool. primary# shutdown -g0 -i0 -y {1} ok boot

5) When you restore ZFS filesystem of the Control Domain and also ZFS filesystems where the Guest Domains are stored, take the steps of (1) and (2) after rebooting the system.

(1) Create disk slice and disk label by using the format(1M) or fmthard(1M) command according to disk partition information you recorded beforehand.

primary# format

Or,

primary# fmthard -s primary-c0t1d0s2.map /dev/rdsk/c0t1d0s2

(2) Create a ZFS storage pool where the Guest Domains are stored.

primary# zpool create -f ldomspool c0t1d0s0

(3) Restore ZFS filesystem within the ZFS storage pool where the Guest Domains are stored.

(Exchange tapes)


primary# zfs receive -Fd ldomspool < /dev/rmt/0n

primary# zfs receive -Fd ldomspool < /dev/rmt/0


C120-E534-15EN B-9

6) Check after Restoration.

Collect the same information as you collected in preparation for system backup ('logfile_get_all_org.txt' in the example) and check whether or not the content is restored correctly. In the following example, logs are stored in 'logfile_get_all_new.txt' with script(1).

primary# script logfile_get_all_new.txt

primary# zpool list

primary# zfs list

primary# zpool get all rpool

primary# zfs get all rpool

C.3 Phase of the Logical Domains P2V Migration Tool

C-4 C120-E534-15EN

C.3 Phase of the Logical Domains P2V Migration Tool

The following sections describe how the conversion from a physical system to a virtual system is performed in each phase.

• Collection Phase • Preparation Phase • Conversion Phase

For information about the notes of each phase, see "C.1.1 Known issue and Notes".

C.3.1 Collection Phase

This phase creates a file system image (archive and manifest) of the source system (physical system). It is necessary to store this data where the target system can access. [Source system]

• Boot the system in single-user mode. • If necessary, copy the ldmp2v command to the source system

If the P2V tool is not installed in a directory that is shared between the source and target systems, you must copy the /usr/sbin/ldmp2v script to the source system.

• Run the "ldmp2v collect" command. ldmp2v(1M) command collects a source system's data and output to the <data-dir>.

source# ldmp2v collect -d <data-dir>

For more information about the command option, see manuals of Oracle Corporation listed in "C.1 Logical Domains P2V Migration Tool Overview".

[Target system] - None.

C.3.2 Preparation Phase

In this phase, "ldmp2v prepare" command creates the Guest Domain on the target system based on the configuration information collected in the collection phase. [Source system]

• None. [Target system]

• Run the "ldmp2v prepare" command on the Control Domain of the target system. target# ldmp2v prepare -d <data-dir> <domain>

For more information about the command option, see manuals of Oracle Corporation listed in "C.1 Logical Domains P2V Migration Tool Overview". Note) If "ldmp2v prepare" command have failed, please run the "ldmp2v -C" command to

remove a domain and virtual devices before running the "ldmp2v prepare" command again.

Example)

target# ldmp2v prepare -C <domain>


C120-E534-15EN C-5

C.3.3 Conversion Phase

In this phase, "ldmp2v convert" command converts the created Logical Domain into a Logical Domain that runs the Solaris 10 OS. Such conversion is done by accessing to the console of the target system and using the standard Solaris upgrade process.

Note) Before you begin the conversion phase, shut down the original physical system, as the Guest Domain uses the same IP addresses, and possibly also the same MAC addresses as the physical system.

[Source system] • Shut down the source system.

[Target system] • Run the "ldmp2v convert" command on the Control Domain of the target system

[Using a local ISO image /install/sol10.iso] target# ldmp2v convert -i /install/sol10.iso -d <data-dir> <domain>

[Using a network installation server]

target# ldmp2v convert -n vnet0 -d <data-dir> <domain>

For more information about the command option, see manuals of Oracle Corporation listed in "C.1 Logical Domains P2V Migration Tool Overview". Note) If some problems happen after Conversion Phase, please back to "C.2 Before Migration"

and follow the migration procedure again after removing the cause of problems.

C.4 After Migration

C-6 C120-E534-15EN

C.4 After Migration

Appendix D How to Remove and install the Logical Domains Manager

C120-E534-15EN D-1

Appendix D. How to Remove and install the Logical Domains Manager

This chapter refers to the case where Oracle Solaris10 is installed in the Control Domain.

D.1 Installing Logical Domains Manager (Logical Domains 1.2 or older)

D.1.1 Unzipping the installation archive

Unzip the installation archive of the downloaded Logical Domains Manager.

localhost# cd /var/tmp

localhost# unzip /net/nfs-server/archives/LDoms_Manager-1_2.zip

Archive: LDoms_Manager-1_2.zip

creating: LDoms_Manager-1_2/

creating: LDoms_Manager-1_2/Install/

inflating: LDoms_Manager-1_2/Install/install-ldm

...

inflating: LDoms_Manager-1_2/README

D.1.2 Starting installer

Start the Logical Domains Manager installer. The security configuration menu by Solaris Security Toolkit (SST) is displayed.

• When selecting [a] Solaris Security Toolkit(SST) set security configuration.

• When selecting [b] Security configuration is not set.

• When selecting [c] A user-specific security driver set security configuration.

Install the Logical Domains Manager according to the security policy for the Control Domain. However, the security configuration of SST affects the installation processing for Enhanced Support Facility (ESF). If the ESF is not installed, select [b]. Immediately after installation of Logical Domains Manager is completed, install the ESF.


D-2 C120-E534-15EN

localhost# cd /var/tmp/LDoms_Manager-1_2/Install

localhost# Install/install-ldm

Welcome to the LDoms installer. You are about to install the domain manager package that will enable you to create, destroy and control other domains on your system. Given the capabilities of the domain manager, you can now change the security configuration of this Solaris instance using the Solaris Security Toolkit. Select a security profile from this list: a) Hardened Solaris configuration for LDoms (recommended) b) Standard Solaris configuration c) Your custom-defined Solaris security configuration profile Enter a, b, or c [a]: a

Select an option for configuration: y) Yes, launch the LDoms Configuration Assistant after install n) No thanks, I will configure LDoms myself later Enter y or n [y]: n

In Logical Domains 1.2 or newer release, a confirmation menu that asks you whether or not you need to configure Logical Domains by Logical Domains Configuration Assistant will appear after the Logical Domains Manager installer starts.

• When [y] is selected Logical Domains Configuration Assistant is used to perform the configuration processing of Logical Domains.

• When [n] is selected Logical Domains Configuration Assistant is not used. To configure Logical Domains, scripts or commands are used after Logical Domains is installed. Note) Select [n]. Fujitsu is not supporting [y].

You must configure the logical domain by selecting [n], and using the script after Logical Domains is installed.

• After installing Logical Domains Manager, the Logical Domains Manager daemon (ldmd) is started automatically.

D.1.3 Confirming installation

The following command is executed to confirm the installation. primary# /opt/SUNWldm/bin/ldm list --------------------------------------------------------------------- Notice: the LDom Manager is running in configuration mode. Configuration and resource information is displayed for the configuration under construction; not the current active configuration. The configuration being built will only take effect after it is downloaded to the system controller and the host is reset. --------------------------------------------------------------------- NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv SP 64 8064M 0.1% 16m

Remarks) • The above Notice message is always displayed until the initial setting of the Control Domain is

completed. • The Control Domain name is "primary".


C120-E534-15EN D-3

D.1.4 Changing the security configuration with the Solaris Security Toolkit (SST)

When selecting [a] of the security configuration menu by SST, the security configuration by SST is executed. SST functions are as follows.

• To stop major network services except for ssh. • Access restrictions to hosts by tcpwrapper, etc. • restrictions for users to cron. • changes to password setting polic.y • collecting access logs.

Even after Logical Domains installation, you can relax security setting using SST. You can change the security configurations by SST according to the application requirements or operations after introducing them. This is the method of accessing using Telnet in cases where there is no device that can use ssh.

primary# svcadm enable svc:/system/filesystem/autofs:default

primary# svcadm enable svc:/network/telnet:default

primary# echo "in.telnetd: ALL" >> /etc/hosts.allow

primary# vi /etc/default/login

The row of "CONSOLE" is commented out.

For allowing command use, please delete relevant user names in allowed user names in /etc/cron.d/at.deny. When setting the security configuration by SST again, the temporary changes for relaxing security setting can be canceled. The security configuration by SST can be always set from the console without Logical Domains Manager installer.

primary# /opt/SUNWjass/bin/jass-execute -q -d ldm_control-secure.driver


If the following messages are displayed during the execution, enter "yes" to continue the processing.

primary# /opt/SUNWjass/bin/jass-execute -q -d ldm_control-secure.driver [NOTE] The following prompt can be disabled by setting JASS_NOVICE_USER to 0. [WARN] Depending on how the Solaris Security Toolkit is configured, it is both possible and likely that by default all remote shell and file transfer access to this system will be disabled upon reboot effectively locking out any user without console access to the system. Are you sure that you want to continue? (yes/no): [no]Yes Executing driver, ldm_control-secure.driver



D-4 C120-E534-15EN
